What it’s like
The place. Spring Grove is a small village in McHenry County where nearly everyone lives in a home they own, and very few households fall below the poverty line. Household incomes run well above the county's, and the typical home is valued at about what you would expect from a place where owners settle in for the long term. The population is middle-aged, and a good share of adults hold a four-year degree. Winters are cold, with January the coldest month and highs staying below freezing, while July brings warm summer highs. Rain and melted snow add up to a moderate amount over the year.
Work. Residents work mostly in schools, hospitals and social care, in shops, in professional and business services, and in manufacturing. Some of the largest workplaces in the village itself are Scot Forge, Jewel Food Stores and Holian Insulation Company. Commutes are on the long side, and a fair number of people work from home. Across McHenry County, unemployment is higher than it was a year earlier, though the county has added a few more jobs than the year before.
Things to do. A short drive away, Chain O' Lakes State Park is a protected area of lakes and woods, Wooster Lake is a quiet lake, and Wilmot Mountain is a ski area for the cold months. A longer drive brings you to Geneva Lake, a large lake, and to Six Flags Great America, an amusement park.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Spring Grove’s census tracts, against the rest of the country; all of them together, relatively low. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on McHenry County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
